Abstract: An automatic measurement system of the 320 meters meteorological tower is described. This system is being designed to provide the vertical structure of the meteorological elements that will meet the research objectives of the air pollution and the atmospheric boundary layer. Sensors to be described are the sensors of temperature at the ground, temperature difference between two levels, wind speed and direction. In addition, the featuxe of automatic data processing system is described. This system can be divided into two groups according to the desired sampling rate. One is for the form of profile of the mean wind speed, wind direction and temperature differece. The other is to sent the instantaneous data and signals of the fast response sensors.
